Abstract: The Lingding Bay, 2110km2 in erea, is situated in the northestern part of the zhujiang River mouth in Guangdong Province. The area abounds in resources of tidal flat soils. Through centuries the inhabitants of the area have built dikes around it and brought it under cultivation. The main crops are rice and sugar cane.The present paper discusses the physico-chemical properties of the soils. Its texture is medium clay. The salt and organic matter contents are generally 0.2-1.5% and 1.5-2.2%, respectively. They are mostly neutral-alkaline in reaction with pH value (between, 6.5-8.0). The natural fertility of the soils is high. The soil data are very useful for the area development, especially for the rational production system of agriculture and fishery. The development prospect of this area is very promising.

Key words: tidal flat soil, developmental pattern, mariculture, reclaimation by embankment
